There are two problems with this operation: firstly, it can be
unobviously dangerous - it can cause conflicts in working copies that
don't have any local modifications:

svn add foo # r10
svn delete --but-not-from-working-copies foo # r18
# Later, we add the file again.
svn add foo # r20

Now anyone with an unmodified wc that updates to each revision in turn
will find that, at r20, their local 'foo' is obstructing the remote
'foo'. This isn't an uncommon pattern - think of continuous build
machines or websites that are updated automatically.

The second problem is a technical one. If someone is at r1 and updates
to r19, they should see the addition of a file that's not version
controlled. We don't have any way to represent that addition.

Malcolm
